Dont really get "gains" from a BOV/BPV. You get more boost holding capability, faster throttle response (if properly set up) and cool noises.

Difference from the hybrid? This is far cooler. Hybrid was 100% VTA, 100% recirc or 50/50. Respons is incrementally adjustable. infinite adjustment from 100% recirc to 100% VTA. Mine is set at approx 65% recirc/35% VTA. Also has an available electronic controller for in car adjustment of vent!

Crazy cool shiznitch.

where can one get this?

I have this bov/bpv on my itsme fmic kit...love it! Let's me choose how annoying I want to be
